flotation plant optimisation

Froth Stability Monitoring – A Route to Automatic Flotation Optimisation The importance of control for the effective operation of float circuits is well known amongst operators of flotation concentrators. Studies have shown that 5-15 % of the valuable minerals are not recovered due to sub-optimal process settings.

plant in Chile, which will be the largest installation of its kind in the world. Also at an Antofagasta operation, Siemens has installed a second 16 m hybrid flotation cell at Minera Los Pelambres (IM, August 2008, p24). In the molybdenum concentrator, it recovers fines lost by conventional flotation cells. Its benefits include:

May 01, 2006 Survey data from a platinum flotation plant, shown in Fig. 1, was used for model regression.The plant is processing a chromite seam of the Bushveld complex, in South Africa. Apart from the chromite, the mineral suite includes typical copper/nickel/platinum sulfide minerals and associated gangue minerals (e.g. silica and talc).

Bench flotation test programmes are commonly designed to consider the following parameters: flotation kinetics, grind size, reagent selection and optimisation, selective flotation (complex sulphides), pulp potential and flowsheet design. Flotation is a physical-chemical process carried out in agitated tanks (cells).

Pilot plant flotation Continuous pilot scale flotation programs can be run in conjunction with comminution, regrind circuits and thickening/filtration to provide crucial information for plant scale operation. our flotation cells range in size from 1.5 to 300L and can be arranged to simulate various circuit configurations from 15 kg/hr to 2 tph.

A fundamental issue with Plant . Optimization is that this can only be carried out if the plant is running in a stable manner. Plant Stability is the platform from which plant optimization can be carried out and as a consequence, plant reviews tend to focus on both plant stability initially followed by Plant Optimization later. A

Jan 11, 2016 On a plant of 250 tons the extra labor would bring it up to approximately 10c. per ton. Actual figures from a large plant of over 2000 tons gave 6.1c. per ton. The flotation feed in this case represents 60% of the crude-ore tonnage or 3.5c. per ton of crude ore treated. FLOTATION THEORIES

a flotation plant may outweigh all of the other uses of water at a mine site, and the need to maintain a water balance is critical for the plant to operate efficiently. Process water may be irretrievably lost or not immediately available for reuse in the beneficiation plant because it has been used in the production of
